His didn't require death, but they didn't give the strength Dio's did, either. Murphy's considering it too, to be honest. What would happen if they both hit up someone. Not that he's out specifically to spitroast someone in thrall bites but if it works out specifically they could get someone real damn useful out of it, maybe.

"I was honestly ready to try it myself if I had to but I wasn't going to tell anyone that. People get a little-" he does a finger gun "-but seeing if both could work? Especially if they were someone we'd want to keep in a fight?"

He sneaks one more bite out of the tupperware before putting a lid on it.

"I know how to counteract my own bite and already ordered a vaccine. I might be able to counteract yours to if I got the right equipment and a blood sample. The two disease experts I ate were both very good at their work. Actually the second one wanted me to do it so I'd remember her skills, too." It's possible he could come up with something to counter Dio's. Or one of those magic purifying thingies could handle it- but honestly he's crazy curious as to what goes into being a vampire and now he has the borrowed intelligence to try and understand it.
